After stopping by Geekbench, the Samsung Galaxy J5 (2017) has been spotted on GFXBench as well. In addition to the specs previously revealed, the GFXBench listing also confirms 16GB storage, and 12MP rear and front cameras.
The listing also reveals a 4.8-inch HD display, but given that the Galaxy J5 (2016) came with 5.2-inch display, it's likely that GFXBench has got the display size wrong. Other key specs listed include Exynos 7870 SoC, 2GB RAM, and Android 7.0.
